FIGURE 7 is a cross-sectional view taken on line 7-7 of FIG. 5; and

FIGURE 8 is a cross-sectional View taken on line 88 of FIG. 5.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring now to the drawings in general and more particularly to FIGURE 1, the heating system of the instant invention is comprised of a burner means indicated generally at 10, a blower 12, a source of fuel oil such as a fuel tank 14, an elongated conduit 16 extending horizontally throughout the length of the brooder 18 and having a cover element 20 supported thereon throughout a major portion of its length and an upwardly extending flue portion 22 vented at 24 outside of the brooder 18.

The fuel tank 14 is supported by a plurality of legs 26 above the floor 28 of the brooder 18 in such a manner that the fuel oil will flow by gravity through the conduit means 31) into the bottom of the burner means 10. (Note FIGURES 4 and 5.) A closure valve 32 may be provided at the outlet from the fuel tank 14 and a regulating means 34 having a valve 36 is interposed in the con duit means 30 to vary the flow of fuel oil therethrough. It is to be understood that any conventional means may be used to regulate the fiow of fuel oil from the tank 14 to the burner means 10.

The burner means 10 includes a casing element 38, cylindrical in shape and preferably formed in two sections having outstanding flange means 40 secured together by bolts 42 or the like. One end of the casing element 38 is substantially closed and has means defining a plurality of spaced draft apertures 4-6 therein and an angular opening 43 for receiving an air intake pipe 50 secured to the blower 12 in a manner and for a purpose to be further described in detail hereinafter. The other end 52 of the casing element 38 is open and in communication with the elongated conduit 16. A shallow depression or the like 54 may be provided around the periphery of the open end 52 of the casing element 38 to allow the elongated conduit 16 to be seated thereon and secured by screws or the like 56.

The elongated conduit 16 is supported along its length by a plurality of spaced bracing members 58 of any conventional form. The cover element 2% is maintained in spaced relation to the elongated conduit 16 by a plu rality of longitudinally spaced saddle members 66 having upturned rims 62 securing the extremities of the cover element 20. Screws or the like 64 may be used to secure the saddle members 60 to the elongated conduit 16. (Note particularly FIG. 2.)

The burner means 10 includes a raised boss member 66 supporting thereon a lower burner element 68 on which is seated in removable relationship a nozzle e'lement 70. The lower burner element 68 preferably has an upper face 72 inclined at a 45 angle and facing the closed end 44 of the casing element "38. An upwardly extending wall member 74 on the lower burner element 68 surrounds a cavity '76 forming the lower part of a V vaporizing chamber for a purpose to be described in further detail hereinafter. A passageway 78 is defined in the lower burner element 68 and communicates at one end with the vaporizing chamber 76 and at its other end with a hollow connector member 80* secured to the conduit means 30 and held in position through an aperture 82 in the boss member 66 and casing element 38 by a washer -84 and lock nut '86 or the like.

The nozzle element 70 has a downwardly extending periphenal flange member 87 overlying the wall member 74 in loose telescoping relationship. A plurality of jet apertures 88 are defined in spaced circumferential relationship on the nozzle member 70 and an upwardly extending central positioning cone 9!) is integral therewith for a purpose to, be further described hereinafter.

The. blower 12 is conventional in form and has an outlet end 2 through which a blast of air is emitted. The air intake pipe 51} is supported a predetermined distance from the outlet end 92 of the blower 12 by a spacer element 94. A flat plate 96 having an opening therein in communication with the outlet end 92 of the blower 12 is secured to a cylindrical sleeve by a plurality of right angled brace members 98, two such brace members 98 being shown for illustnative convenience. The cylindrical sleeve 10% fits in telescoping relationship over the inlet end of the air intake pipe 50. Any conventional fastening means, such as nuts and bolts 102, may be used Patented Oct. 15, 1963- to secure the flat ring 96 and the sleeve 100 to the braces 98 so that the blower 12 may be easily and quickly slid into fixed relationship over the air intake pipe 50. Open ings 99 are left between the brace members 98 of the spacer element 94 for the intake of air if the blower should become disabled.

The outlet end of the air intake pipe 56 has a positioning element 104 supported therein by a pair of diametrical braces 106 leaving openings 108 for the passage of air. (Note particularly FIGURE 6.) The positioning element 164 has a recess 110 engageable over the positioning cone 90 on the nozzle element 70 to space the outlet end of the air intake pipe 56 from the nozzle element 7t) and to quickly position these elements in relationship to each other.

An igniting trough 112 is defined in the boss 66 surrounding the lower burner element 68 and has a groove 114 to allow excess fuel oil to flow into a reservoir 116 from which an overflow pipe 118 carries the same to any convenient location. It is to be understood that only a relatively small amount of fuel oil will normally reach the overflow pipe 118, but that if it is desired, this material may be pumped back to the fuel tank 14.

A dam member 120 is provided within the casing element 38 and extends above the level of the overflow pipe 118 so that fuel oil will not be carried into the elongated conduit 16.

Any conventional support means 122 may be provided to hold the burner means 10 in spaced relation to the floor 28 of the brooder 18.

The use and operation of the device of the instant invention will now be apparent. Fuel oil stored in the tank 14 is allowed to flow through the closure valve 32, the conduit means 36 and the regulating means 35 into the burner means 10 wherein a small amount of it will flow over the wall member 74 on the lower burner element 68 and/or through the apertures 88 in the nozzle element 70 to the igniting trough 112. A separate opening may be provided in the casing element 38, or the blower 12 and the air intake pipe 50 may be withdrawn from the opening 48 to allow any conventional means to be inserted therethrough for igniting the fuel oil in the trough 112. Once this has been accomplished and the lower burner element 68 is heated to a suflicient degree, the fuel oil coming from the fuel tank 14 into the chamber 76 will be vaporized and a plurality of jets of flame will pass through the apertures 88 in the nozzle 70. The small amount of fuel oil which has overflowed into the igniting trough 112 and the reservoir 116 will be quickly consumed. A positive draft may then be provided to blow the heated air surrounding the nozzle member 70 through the elongated conduit 16, the vertically extending flue 22 and out the vented end 24 by reinserting the air intake pipe 50 until the recess 110 in the positioning element 164 is seated over the positioning cone 90 on the nozzle element 70. It will be noted that since the upper surface of the lower burner element 68 is on a 45 angle, the air coming from the blower 12, will force the heat in a forward direction, whereas if the burner means were vertically extending, the draft would blow the heat downwardly against the casing element 38 rather than towards the elongated conduit 16.

The burner means 110 may be easily cleaned by simply removing the blower 12 and the air intake pipe 50 and lifting the nozzle element 70 from its seated relationship on the wall member 74. A small nail, wire or drill bit may then be inserted through the apertures 88 in the nozzle element 70 to clean the same.

'It will now be seen that there is herein provided a device which provides all of the objectives of the instant invention and others, including many advantages of great practical utility and commercial importance.

Since many embodiments may be made of this inventive concept, and since many modifications may be made of the embodiments hereinbefore shown and described it is 4 to be understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.
